The liner is one year old 20 mil I think. The ants put another hole in the liner about a foot away from the first cluster of holes. We are in a severe draught so they are quite happy with their new water source. They have tunned under the pool. I guess I've got quite a battle patching holes and killing some ants. I won't give up it was 102 yesterday. I have seen too above ground pools blow out in our area. I think thirsty plants and bugs are just doing what they need to survive.
